1 Claim.

The invention relates to an improvement in gas stoves or ranges of the type in which the burners are equipped with manifoldand valve connections through which gas is fed to the burners and controlled. Owing to the proximity of the valves to the burner chamber the heat from the chamber often seriously affects the proper operation of the valves causing them to stick. Where the manifold and valves are housed the difficulty is increased owing to the retention of the hot air around the valves, to say nothing of the fact that the hot air is apt to disfigure the housing, customarily enamelled as it is on its outside face.

The invention can best be seen and understood by reference to the drawings, such portion of the stove or range only being shown as is necessary for a proper understanding of the invention.

Figure l is a plan.

Fig. 2 is a front elevation.

Fig. 3 is an inverted plan of that shown in Fig. 1.

Fig. 4 is a section on the line 44 of Fig. 2.

Fig. 5 is a section on the line 5-5 of Fig. 2, and

Fig. 6 is a section on the line 66 of Fig. 2.

Referring to the drawings 1 represents the top of the stove, 2 its front, and 3 the burner chamber within which the burners 4 are arranged. Leading to the burners are the usual fuel supply pipes 5 having mixing chambers 6 at their outer ends into which gas and air are directed to pass. Located forward of the mixing chambers 6 are valves 7 through which gas is directed to the mixing chambers of the respective burners and controlled. The valves connect with a gas manifold 8 common to all the valves, and lying above the valves. The valves are also provided with the customary nipples 9 leading into the mixing chambers of the respective burners.

The valves '7 and manifold 8 are preferably located outside the body of the stove or forward of and parallel with the front of the stove, the manifold being horizontally arranged and the valves aligned beneath it. The marginal edge portion 10 of the top adjacent the manifold and valves is extended over the manifold out of contact therewith and provided with a downturned edge 11 which turns around the manifold out of co htact with it. The marginal edge portion 10 has an opening through it to the atmosphere, this opening preferably taking the form of a line of openings 12 lying above the manifold and preferably just back of the manifold.

Co-operating with the marginal edge portion 10 of the top and its downturned edge 11 to form a housing concealing the manifold and valves is a plate 15. This plate extends in front of the manifold and valves out .of contact therewith, the ends of the plate being brought around or round. ed to connect with the front of the stove. The plate 15 where it co-ordinates with the downturned edge 11 preferably extends from a point just inside the outer extremity of this edge and removed from it so as to leave a space 16 through which atmospheric air may enter the chamber of the housing. Inasmuch as the plate 15 is ar ranged forward of the front of the stove, connecting therewith only at its ends, anopening 18 is left at the bottom of the housing through which atmospheric air may enter the chamber of the housing. The plate 15 is provided with openings 19 in it through which the stem 20 of the valve extends, and secured to the ends of these stems outside the plate 15 are handles 21 by which the valves may be turned. The plate 15 has also an opening 19 in it for receiving a push button 22 which controls a pilot light valvular connection 22 The plate 15 is held in place by inside brackets 23. These brackets are fastened by connections 24 to the marginal top portion 10 of the stove, while the plate 15 is secured to the brackets by fastenings 25. The brackets assist also in the support of the manifold, each being rounded to form a cradle 26 in which the manifold lies.

Located back of the manifold and valves and between them and the burners is a plate 28. This plate extends from a point within the burner chamber adjacent the nearest set of burners, and inclines upwardly and outwardly beneath the top edge portion 10 in the stove with extension by the openings 12 therein. In other words, the plate is arranged to divert the heated air from the burner chamber which otherwise might pass into the chamber of the housing containing the manifold and valves, and direct it in the direction of the openings 12. The location and extension of the plate is also such that its end 29, preferably located between the manifold and the openings 12, will lie spaced from the marginal edge portion 10 of the top and leave an opening 30 through which air within the chamber of the housing may pass to said openings. The plate 28 is fastened to the brackets 23 by fastenings 31, offsets 32 being formed in the plate for the purpose of facilitating such fastening.

In the operation of the ordinary gas stove, where the manifold and valves are concealed by a housing, hot air and gases from the burner chamber will pass outwardly into the chamber of the housing heating the valves and disfiguring the front face of the housing which customarily forms an enamelled part of the stove. The heating of the chamber of the housing is increased by the fact that the valves and valvular connections will become heated by conduction of heat. This heating of the chamber of the housing, together with the valves and valvular connections contained within it, is not obviated even when openings to the atmosphere are formed in the housing inasmuch as the heated air can only escape by way of these openings, especially in the top portions of the housing chamber, and accordingly will prevent entrance of atmospheric air. The present arrangement contemplates the diversion of hot air and gases from the chamber of the housing in so far as possible coupled with a constant scouring and cooling of the chamber with atmospheric air.

The general operation is as follows: Hot air and gases from the burner chamber which might otherwise enter the chamber of the housing are diverted therefrom to pass through the openings 12 in the top edge portion 10 of the stove lying between the nearest set of burners and the chamber of the housing and above this chamber. The passage of this heated air through the openings 12 will at the same time tend to draw air from the chamber of the housing in consequence of which atmospheric air will enter the chamber of the housing and pass to said openings thereby scouring the chamber of the housing of heated air and keeping the chamber cool. This operation is facilitated by the plate 28. This plate owing to its location acts to prevent hot air and gases from the burner chamber from passing into the chamber of the housing and will divert it in the direction of the openings 12 to pass through these openings. Inasmuch as the end 29 of the plate is spaced from the adjacent edge portion of the top containing the openings, air from the chamber of the housing will be permitted to pass by the end of the plate to said openings, the operation being otherwise the same as before.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States In a gas stove having a top, a burner chamber, a burner within said chamber and burner connections including a manifold and valve; the combination therewith of a housing for the manifold and valve positioned with its top portion in the same plane with and abutting said first mentioned top, the portion of said housing top lying adjacent said burner chamber being formed with openings, the lower portion of said housing being formed with an opening lying beneath said manifold and valve, a deflecting plate positioned Within said housing and burner chamber and sloping upwardly from said burner chamber into said housing, the edge of said plate Within said housing being spaced from the top and front thereof and extending forwardly beyond said openings in the top of the housing.
